Maybe you could try ClipGrab:

Another alternative is Flash Video Downloader 2:

They're both standalone FLV downloaders that work with almost any video website. Then you'll just have to convert the FLV file to another format (if you need that) with Evom, iSquint, VideoVangelist, iVideoConverter or other any video converter.
